Having just spent five days hiking up in England’s glorious Lake District, I’ve got a new found commitment to exercise. True, we spent a fair bit of our holiday touring pubs, napping and watching movies. But it was really invigorating to wake up every day and take a long hike as a family.

So I’m always keen to learn about new strategies for keeping we mere mortals healthy. To that end, here are five new trends in exercise:

1. Barefoot Running. Not surprisingly, perhaps, I learned about this one from my husband. Apparently, the new rage in running is to do it barefoot. Why is that, you ask? According to the experts, one of the reasons that running is such an injury-prone sport is that when we wear running shoes, we are actually training our feet to run in a way that is neither natural nor good for them. Specifically, while running shoes force your heel to hit the ground first with a force equal to as much as three times your body weight, “natural” – i.e. barefoot – running encourages a low-impact strike on the ball of your foot. Among other things, this natural running technique explains why Kenyans have consistently been such great distance runners. Barefoot running provides comfort, safety and best of all…it’s free!

2. High Intensity Training. Here’s another new trend in exercising, also courtesy of my husband (Coincidence? Maybe.) New research suggests that many of us could benefit from as little as three minutes of high intensity training (HIT) a week. That’s right, three minutes. So, for example, you get on an exercise bike, warm up by doing gentle cycling for a couple of minutes, then go flat out for 20 seconds. Then wait a couple of minutes and do another full-intensity 20-second work out. Then take one more break and a final 20 seconds going all out. Why does this work? There are two reasons. On the one hand, when you do HIT, you are using not just the leg muscles, but the upper body as well (including arms and shoulders), so that 80% of the body’s muscle cells are activated, compared to 20-40% for moderate intensity jogging or cycling. Active exercise also helps your body break down its stores of glucose (sugar). Great news for the time-pressed among us. And really, who isn’t pressed for time?

3. The Nano Workout. In a similar time-saving vein, but engineered to induce far less sweat, is the Nano Workout. The Nano Workout is the brainchild of Joakim Christoffersson, and is premised on the idea that many of us don’t have the time, energy or ambition to spend hours on end at the gym. Instead, Christofferson offers a series of exercises that are “based on the situation you are in and using the natural conditions the situation provides.” The idea is that by breaking down your day and analyzing the most common situations you find yourself in – whether at the desk, in the kitchen, or on the bus – you can achieve a more healthy life, no matter what your day looks like. So the next time you’re watching TV, try that hip flexor. There’s no time like the present.
